Part Overview

The TE Connectivity AMP Connectors 1776137-9 is a 9-position terminal block header with male pins, shrouded on four sides, designed for 90-degree right-angle through-hole mounting. This component operates at 300 V UL and 11 A UL current rating with an operating temperature range of -40°C to 110°C. The part is manufactured from polyamide (PA) nylon housing with phosphor bronze contacts and tin mating finish. The 1776137-9 maintains active product status and is RoHS compliant with MSL 1 (unlimited moisture sensitivity level). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements permit functional alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity AMP Connectors 1776137-9 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Number of positions: 9
• Pitch: 0.150" (3.81mm)
• Header orientation: 90°, right angle
• Type: Header with male pins, shrouded (4 side)
• Mounting type: Through hole
• Insulation height: 0.285" (7.25mm)

Electrical Compatibility:

• Voltage rating: 300 V UL minimum
• Current rating: 8 A UL minimum (substitute may be lower than main part's 11 A)
• Termination style: Solder
• Contact mating finish: Tin

Compliance & Environmental:

• Material flammability rating: UL94 V-0
• RoHS compliance status: Active
• MSL: 1 (Unlimited)

The Phoenix Contact 1827936 qualifies as a substitute based on matching all mechanical parameters, meeting or exceeding electrical requirements (300 V UL, 8 A UL), maintaining UL94 V-0 flammability rating, and confirming RoHS3 compliance with MSL 1 status. The substitute accommodates the same PCB footprint, connector interface, and environmental operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TE Connectivity AMP Connectors 1776137-9 is the specified component and remains the first choice for new designs and existing applications. This part is active in production, RoHS compliant, and carries full UL certification at 11 A UL current rating.

Substitute Part Selection: The Phoenix Contact 1827936 serves as a qualified substitute when the primary part is unavailable. This substitute maintains mechanical and electrical compatibility through identical pitch (0.150" / 3.81mm), header orientation (90° right angle), position count (9), and insulation height (0.285" / 7.25mm). Both parts meet UL94 V-0 flammability requirements and operate at 300 V UL. The substitute carries ROHS3 compliance and MSL 1 status, confirming environmental and regulatory equivalence.

Current Rating Consideration: The Phoenix Contact 1827936 operates at 8 A UL, which is lower than the primary part's 11 A UL rating. Applications requiring the full 11 A capacity must use the TE Connectivity 1776137-9. Applications operating at or below 8 A UL current may use the substitute without derating.

Housing Material Difference: The primary part uses polyamide (PA) nylon housing, while the substitute uses polybutylene terephthalate (PBT). Both materials achieve UL94 V-0 flammability rating. PBT offers enhanced chemical resistance and dimensional stability. This material difference does not affect electrical or mechanical compatibility for standard applications.

Contact Tail Length Variation: The primary part has a contact tail length of 0.122" (3.10mm), while the substitute measures 0.134" (3.40mm). This 0.012" (0.30mm) difference requires verification of PCB pad layout and solder joint clearance during substitution to ensure proper solder fillet formation and mechanical integrity.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1827936 be used as a direct replacement for the TE Connectivity 1776137-9?

A: The Phoenix Contact 1827936 qualifies as a substitute for applications operating at 8 A UL or below. The primary part's 11 A UL rating is not matched by the substitute. Mechanical compatibility is confirmed through identical pitch (0.150" / 3.81mm), position count (9), header orientation (90° right angle), and insulation height (0.285" / 7.25mm). Both parts maintain UL94 V-0 flammability and 300 V UL voltage rating. Verify current requirements and PCB pad layout before substitution.

Q: What is the impact of the contact tail length difference between these parts?

A: The TE Connectivity 1776137-9 has a contact tail length of 0.122" (3.10mm), while the Phoenix Contact 1827936 measures 0.134" (3.40mm). This 0.012" (0.30mm) difference affects solder joint geometry and PCB pad design. Verify that existing PCB pad layouts accommodate the longer tail length of the substitute to ensure proper solder fillet formation and mechanical strength.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 1776137-9 is RoHS compliant. The Phoenix Contact 1827936 is ROHS3 compliant. Both parts meet RoHS requirements and carry MSL 1 (unlimited) moisture sensitivity level status.

Q: What is the difference between the housing materials?

A: The TE Connectivity 1776137-9 uses polyamide (PA) nylon housing. The Phoenix Contact 1827936 uses polybutylene terephthalate (PBT) housing. Both materials achieve UL94 V-0 flammability rating. PBT provides enhanced chemical resistance and dimensional stability compared to polyamide. This material difference does not affect electrical or mechanical compatibility for standard terminal block applications.

Q: Do both parts have the same voltage and current ratings?

A: Both parts are rated at 300 V UL. The TE Connectivity 1776137-9 is rated at 11 A UL, while the Phoenix Contact 1827936 is rated at 8 A UL. The substitute also carries an IEC rating of 8 A at 250 V. Applications requiring the full 11 A capacity must use the primary part. Applications operating at 8 A or below may use the substitute.

Q: What are the key mechanical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: number of positions (9), pitch (0.150" / 3.81mm), header orientation (90° right angle), type (header with male pins, shrouded 4 side), mounting type (through hole), and insulation height (0.285" / 7.25mm). Both the primary part and substitute match these parameters exactly.

Q: Are there any packaging differences between these parts?

A: The TE Connectivity 1776137-9 packaging is not specified in the provided data. The Phoenix Contact 1827936 is supplied in bulk packaging. Confirm packaging requirements with your supplier before ordering.

Q: What certifications do both parts carry?

A: Both parts carry UL94 V-0 material flammability rating, confirming suitability for applications requiring flame-retardant components. Both are assigned ECCN EAR99 and HTSUS 8536.69.4040 classifications. The TE Connectivity 1776137-9 is RoHS compliant. The Phoenix Contact 1827936 is ROHS3 compliant. Both maintain MSL 1 (unlimited) moisture sensitivity level.
