TE Connectivity AMP Connectors 1776134-9 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1776134-9 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 brass contacts and tin mating finish, classified as UL94 V-0 flammability rated and RoHS compliant. The product maintains active status in the Buchanan series. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility is required within compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block headers is determined by strict equivalence across electrical and mechanical parameters. The primary criteria for substitution include:

Electrical Compatibility: Voltage rating (300 V UL minimum), current rating (8 A UL minimum for the substitute), contact material composition, and mating finish (tin).

Mechanical Compatibility: Number of positions (9), pitch spacing (0.138" / 3.50mm), header orientation (90-degree right angle), mounting type (through hole), termination style (solder), contact tail length (0.134" / 3.40mm), and insulation height (0.285" / 7.25mm).

Regulatory Compliance: UL94 V-0 flammability rating, RoHS compliance status, and ECCN classification (EAR99).

The Phoenix Contact 1844281 terminal block header qualifies as a substitute based on matching all mechanical dimensions, maintaining equivalent electrical performance within specified UL ratings, and meeting identical regulatory compliance requirements. Housing material differs (polybutylene terephthalate versus polyamide), and color differs (green versus black), but these variations do not affect functional substitution in applications where the primary part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1776134-9 and Phoenix Contact 1844281 terminal block headers are active products with equivalent mechanical and electrical specifications suitable for 9-position, 3.5mm pitch, 90-degree right-angle through-hole applications. Selection between these components is based on availability, supply chain considerations, and application-specific requirements.

The TE Connectivity 1776134-9 provides an 11 A UL current rating with polyamide housing and black color designation. The Phoenix Contact 1844281 provides an 8 A UL current rating with polybutylene terephthalate housing and green color designation. Both components meet UL94 V-0 flammability requirements, maintain 300 V UL voltage ratings, and comply with RoHS and EAR99 export control classifications.

For applications requiring the maximum UL current rating of 11 A, the TE Connectivity 1776134-9 is the appropriate selection. For applications operating at 8 A UL or below, either component is functionally equivalent. Housing material selection (polyamide versus polybutylene terephthalate) may be determined by specific environmental or thermal requirements not specified in the provided parameters.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1844281 be used as a direct replacement for the TE Connectivity 1776134-9?

A: The Phoenix Contact 1844281 is mechanically and electrically compatible for applications operating at 8 A UL or below. Both components feature identical 9-position, 3.5mm pitch, 90-degree right-angle through-hole configurations with matching contact tail lengths and insulation heights. The primary difference is the UL current rating: 11 A for the TE Connectivity part versus 8 A for the Phoenix Contact part. Application current requirements determine substitution suitability.

Q: What are the key mechanical parameters that must match for terminal block header substitution?

A: Critical mechanical parameters include number of positions (9), pitch spacing (0.138" / 3.50mm), header orientation (90-degree right angle), mounting type (through hole), contact tail length (0.134" / 3.40mm), and insulation height (0.285" / 7.25mm). These parameters ensure physical compatibility with mating connectors and printed circuit board layouts.

Q: Are there differences in housing material between these two parts?

A: Yes. The TE Connectivity 1776134-9 uses polyamide (PA) nylon housing, while the Phoenix Contact 1844281 uses polybutylene terephthalate (PBT) housing. Both materials meet UL94 V-0 flammability requirements. Material selection may affect thermal performance and chemical resistance in specific environments.

Q: Do both parts meet the same regulatory compliance standards?

A: Both components are RoHS compliant (TE Connectivity is RoHS Compliant; Phoenix Contact is ROHS3 Compliant), classified as EAR99 for export control, and assigned the same HTSUS code (8536.69.4040). Both maintain UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels.

Q: What is the voltage rating for both terminal block headers?

A: Both components are rated for 300 V UL. The Phoenix Contact 1844281 additionally provides IEC ratings of 250 V, which are not specified for the TE Connectivity 1776134-9.

Q: How do the current ratings compare between these parts?

A: The TE Connectivity 1776134-9 is rated for 11 A UL, while the Phoenix Contact 1844281 is rated for 8 A UL. The Phoenix Contact part also provides an IEC current rating of 12 A. Application current requirements determine which part is appropriate for a given design.

Q: Are the contact materials the same?

A: Both components feature tin mating finish. The TE Connectivity 1776134-9 specifies brass contact material. The Phoenix Contact 1844281 does not specify contact material in the provided parameters.

Q: What is the operating temperature range?

A: The TE Connectivity 1776134-9 operates from -40°C to 110°C. Operating temperature range is not specified for the Phoenix Contact 1844281 in the provided parameters.
