Substitute Part Grouping Explanation

Substitution of the TE Connectivity 282812-7 with the Amphenol PCD ELFH07220 is based on electrical and mechanical parameter alignment within acceptable tolerances for terminal block header applications. Both parts share the following critical substitution criteria:

Matching Parameters:

• 7-position configuration with single level
• 90° right-angle header orientation
• Male pin shrouded (2 side) design
• Through-hole solder termination
• 15 A current rating (UL)
• 300 V voltage rating (UL)
• Tin contact mating finish
• UL94 V-0 flammability rating
• MSL 1 (unlimited moisture sensitivity)
• EAR99 export classification

Allowable Variations:

• Pitch tolerance: 0.197" (5.00mm) to 0.200" (5.08mm) — within standard connector pitch tolerance
• Operating temperature: 282812-7 rated to 110°C; ELFH07220 rated to 105°C — both support standard industrial applications
• Housing material: Polyamide (PA66) versus Polybutylene Terephthalate (PBT) — both meet UL94 V-0 requirements
• Contact material: Copper alloy versus brass — both provide equivalent electrical conductivity and tin plating compatibility
• Contact tail length: 0.138" (3.50mm) versus 0.155" (3.94mm) — both accommodate standard PCB through-hole spacing

Parameter Comparison

Engineering Selection Recommendations

Primary Part: TE Connectivity 282812-7

The 282812-7 is the specified component and maintains active product status with ROHS3 compliance. This part is suitable for applications requiring the full operating temperature range of -40°C to 110°C. The polyamide (PA66) housing and copper alloy contacts provide the specified material composition. Current inventory of 825 pieces supports immediate procurement.

Substitute Part: Amphenol PCD ELFH07220

The ELFH07220 is a direct functional equivalent with active product status and RoHS compliance. This substitute is appropriate for applications where the maximum operating temperature does not exceed 105°C. The polybutylene terephthalate (PBT) housing and brass contacts deliver equivalent electrical performance with UL94 V-0 flammability certification. The pitch tolerance of 0.200" (5.08mm) versus 0.197" (5.00mm) is within standard connector manufacturing tolerances and does not affect PCB layout compatibility. Current inventory of 1,066 pieces provides enhanced availability. The ELFH07220 is packaged in trays, whereas the 282812-7 is supplied in bulk.

Compliance and Certification:

Both parts meet the following regulatory and compliance requirements:

• UL94 V-0 flammability rating
• RoHS compliance (282812-7: ROHS3; ELFH07220: RoHS)
• EAR99 export classification
• MSL 1 (unlimited moisture sensitivity)
• 300 V UL voltage rating
• 15 A UL current rating

Selection between these parts should be based on application temperature requirements, packaging preference, and material composition specifications for the end application.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol PCD ELFH07220 be used as a direct replacement for the TE Connectivity 282812-7 in all applications?

A: The ELFH07220 is functionally equivalent for applications where the maximum operating temperature does not exceed 105°C. The 282812-7 supports operation to 110°C. Both parts meet identical electrical ratings (15 A, 300 V), flammability standards (UL94 V-0), and compliance requirements. The pitch difference of 0.003" (0.08mm) is within standard connector tolerance and does not affect PCB compatibility.

Q: What is the significance of the pitch difference between 0.197" (5.00mm) and 0.200" (5.08mm)?

A: The pitch difference of 0.003" (0.08mm) represents a 0.16% variation and falls within standard connector manufacturing tolerances. Both pitches are recognized industry standards for 5mm-class terminal block headers. PCB layouts designed for either pitch accommodate this tolerance without modification.

Q: Are there material compatibility concerns when substituting between polyamide (PA66) and polybutylene terephthalate (PBT) housings?

A: Both polyamide (PA66) and polybutylene terephthalate (PBT) are engineering thermoplastics rated UL94 V-0. Material selection depends on application-specific requirements such as chemical resistance, moisture absorption, and thermal cycling performance. Both materials are suitable for standard industrial terminal block applications. Consult material datasheets for specialized chemical or environmental exposure conditions.

Q: Does the contact material difference between copper alloy and brass affect electrical performance?

A: Both copper alloy and brass provide equivalent electrical conductivity and are compatible with tin plating. The contact mating finish (tin) is identical for both parts, ensuring consistent contact resistance and corrosion protection. Material selection does not impact electrical performance in standard applications.

Q: What packaging differences exist between these parts?

A: The TE Connectivity 282812-7 is supplied in bulk packaging with 825 pieces in stock. The Amphenol PCD ELFH07220 is supplied in tray packaging with 1,066 pieces in stock. Packaging format may affect handling, storage, and integration into automated assembly processes. Confirm packaging requirements with procurement specifications.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet UL94 V-0 flammability certification, RoHS compliance, and MSL 1 (unlimited moisture sensitivity) requirements. Both are rated for 300 V and 15 A under UL standards. Application suitability depends on specific reliability requirements, environmental conditions, and industry standards (aerospace, medical, automotive, etc.). Consult application-specific qualification requirements and component datasheets.

Q: What is the contact tail length difference, and does it affect PCB mounting?

A: The 282812-7 has a contact tail length of 0.138" (3.50mm), while the ELFH07220 has 0.155" (3.94mm). This 0.017" (0.44mm) difference is within standard PCB through-hole tolerance and does not affect mounting compatibility. Both lengths accommodate typical PCB thickness and solder joint formation.

Q: Can these parts be used interchangeably in existing designs without PCB modification?

A: Yes, both parts are mechanically and electrically compatible for through-hole PCB mounting without design modification. The pitch tolerance, contact tail length variation, and insulation height difference are all within standard connector specifications. Verify application temperature requirements to confirm the ELFH07220's 105°C maximum rating is acceptable.
