TE Connectivity AMP Connectors 282812-9 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 282812-9 is a 9-position terminal block header with male pins, shrouded on 2 sides, designed for 90° right-angle through-hole mounting. This component operates at 15 A (UL) and 300 V (UL) with a 5.00mm pitch and is constructed from polyamide (PA66) housing with copper alloy contacts. The part is currently active in production with 936 units in stock and carries ROHS3 compliance and UL94 V-0 flammability rating.

Equivalent and substitute parts are identified to provide design flexibility when the primary part is unavailable, when alternative sourcing is required, or when design specifications allow for compatible alternatives that meet the same electrical and mechanical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block headers is determined by electrical compatibility and mechanical fit within the PCB assembly. The critical parameters that govern substitution are:

Electrical Parameters:

• Current rating (UL): 15 A minimum
• Voltage rating (UL): 300 V minimum
• Contact material and mating finish compatibility

Mechanical Parameters:

• Number of positions: 9 positions required
• Pitch tolerance: 5.00mm nominal (5.08mm represents a 0.08mm variance, approximately 1.6% tolerance)
• Header orientation: 90° right-angle configuration
• Termination style: Solder through-hole
• Mounting type: Through-hole PCB mounting
• Flammability rating: UL94 V-0 minimum

Environmental & Compliance Parameters:

• Operating temperature range: -40°C minimum to 105°C minimum
• RoHS3 compliance required
• ECCN and HTSUS classification alignment

The Amphenol PCD ELFH09210 meets all critical electrical and mechanical substitution criteria. The pitch variance of 0.08mm (5.08mm vs. 5.00mm) falls within standard PCB layout tolerances for terminal block headers. Both parts are rated for 15 A at 300 V, feature 9-position solder-through-hole mounting, and maintain UL94 V-0 flammability compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: TE Connectivity 282812-9

The TE Connectivity 282812-9 is the specified component and remains the first choice when available. It is an active product with established supply (936 units in stock), carries full ROHS3 compliance, and operates across the full temperature range of -40°C to 110°C.

Substitute Part: Amphenol PCD ELFH09210

The Amphenol PCD ELFH09210 is a qualified substitute when the primary part is unavailable. Both parts meet identical electrical specifications (15 A at 300 V), feature 9-position solder through-hole mounting, and carry UL94 V-0 flammability certification and ROHS3 compliance.

Substitution Considerations:

The ELFH09210 exhibits the following differences that must be evaluated within the context of the application:

1. Pitch Tolerance: The 0.08mm pitch variance (5.08mm vs. 5.00mm) is within standard PCB layout tolerances for terminal block headers and does not preclude mechanical compatibility on standard PCB designs.

2. Operating Temperature: The ELFH09210 is rated to 105°C maximum, compared to 110°C for the 282812-9. Applications requiring operation above 105°C must use the primary part.

3. Housing Material: The ELFH09210 uses PBT polymer versus PA66 for the primary part. Both materials meet UL94 V-0 requirements. PBT offers superior chemical resistance; PA66 offers superior mechanical strength. Material selection depends on environmental exposure.

4. Contact Material: The ELFH09210 uses brass contacts versus copper alloy for the primary part. Both materials are tin-plated and suitable for 15 A solder connections. Brass offers superior corrosion resistance in humid environments.

5. Shrouding Configuration: The ELFH09210 provides 4-side shrouding versus 2-side shrouding on the primary part, offering enhanced electrical isolation and mechanical protection.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol PCD ELFH09210 be used as a direct replacement for the TE Connectivity 282812-9?

A: The ELFH09210 is a functional substitute for applications where the operating temperature does not exceed 105°C and the 0.08mm pitch variance is acceptable within PCB layout tolerances. Both parts meet identical electrical ratings (15 A, 300 V), feature 9-position solder through-hole mounting, and carry UL94 V-0 and ROHS3 compliance. Verification of PCB footprint compatibility is required before substitution.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The 0.08mm variance represents approximately 1.6% tolerance and falls within standard manufacturing tolerances for terminal block headers. This difference is typically accommodated in PCB design through standard pad sizing and layout practices. However, PCB artwork must be verified to confirm the substitute part footprint is compatible with the existing design.

Q: Why does the Amphenol part have a lower maximum operating temperature?

A: The ELFH09210 is rated to 105°C maximum, while the 282812-9 is rated to 110°C. This 5°C difference reflects the thermal characteristics of the PBT housing material used in the Amphenol part versus the PA66 material in the TE part. Applications requiring sustained operation above 105°C must use the primary TE Connectivity part.

Q: What is the difference between 2-side and 4-side shrouding?

A: The TE Connectivity 282812-9 features shrouding on 2 sides (typically top and bottom), while the Amphenol ELFH09210 features shrouding on all 4 sides. Four-side shrouding provides enhanced electrical isolation between adjacent contacts and improved mechanical protection. This is a functional improvement that does not compromise compatibility but may affect PCB layout spacing requirements.

Q: Are both parts RoHS3 compliant?

A: Yes, both the TE Connectivity 282812-9 and the Amphenol PCD ELFH09210 are ROHS3 compliant. Both parts also carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory and trade compliance alignment.

Q: What is the difference between copper alloy and brass contacts?

A: The TE Connectivity 282812-9 uses copper alloy contacts, while the Amphenol ELFH09210 uses brass contacts. Both are tin-plated for solder compatibility and carry identical 15 A current ratings. Brass offers superior corrosion resistance in humid or chemically aggressive environments, while copper alloy offers slightly higher electrical conductivity. Both materials are suitable for the specified 15 A solder connection application.

Q: Can I use the Amphenol part if my PCB is already designed for the TE Connectivity part?

A: PCB compatibility must be verified before substitution. The 0.08mm pitch difference and different shrouding configuration may require PCB artwork review. Contact your PCB design team to confirm that the ELFH09210 footprint is compatible with the existing PCB layout before proceeding with substitution.

Q: What inventory is available for each part?

A: The TE Connectivity 282812-9 has 936 units in stock. The Amphenol PCD ELFH09210 has 941 units in stock. Both parts are available as new original components in bulk packaging.
