TE Connectivity AMP Connectors 1776140-7 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1776140-7 is a 7-position terminal block header with male pins, shrouded on two sides, featuring a 0.197" (5.00mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as an active product and is used in applications requiring solder-terminated electrical connections with rated capacity of 15 A at 300 V. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component selection from multiple manufacturers meeting the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the 1776140-7 are identified based on functional equivalence across critical electrical and mechanical parameters. The primary criteria for substitution include: 7-position configuration, 90° right-angle header orientation, male pin shrouded design, solder termination, through-hole mounting, 15 A current rating at 300 V, UL94 V-0 flammability rating, and RoHS compliance. The Amphenol PCD ELFH07220 meets these core requirements with the following considerations: pitch specification of 0.200" (5.08mm) versus the primary part's 0.197" (5.00mm), operating temperature range of -40°C to 105°C versus -40°C to 110°C, and contact material composition of brass versus copper alloy. These variations remain within acceptable tolerance for terminal block header applications where mechanical and electrical performance are preserved.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1776140-7 and Amphenol PCD ELFH07220 are active products with RoHS compliance and identical electrical ratings of 15 A at 300 V. Selection between these components is determined by application-specific mechanical constraints and environmental operating conditions. The 1776140-7 provides an operating temperature range extending to 110°C and features a copper alloy contact material with polyamide housing. The ELFH07220 operates to 105°C maximum temperature with brass contacts and polybutylene terephthalate housing. Pitch tolerance differences of 0.003" (0.08mm) between the two parts require verification against printed circuit board layout specifications. Contact tail length and insulation height variations necessitate evaluation against mounting clearance requirements. Both components satisfy UL94 V-0 flammability classification and unlimited moisture sensitivity rating, confirming suitability for standard industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the ELFH07220 be used as a direct replacement for the 1776140-7 in all applications?

A: The ELFH07220 functions as an electrical equivalent with identical current and voltage ratings. Mechanical compatibility depends on printed circuit board hole spacing tolerance and clearance requirements. The pitch difference of 0.003" (0.08mm) and variations in contact tail length and insulation height must be evaluated against specific board design parameters.

Q: What is the significance of the pitch specification difference between these parts?

A: The 1776140-7 specifies 0.197" (5.00mm) pitch while the ELFH07220 specifies 0.200" (5.08mm) pitch. This 0.003" (0.08mm) difference affects hole spacing on the printed circuit board. Substitution is valid only when the receiving board accommodates the ELFH07220 pitch specification or when design flexibility permits board modification.

Q: Are there temperature operating range limitations when substituting the ELFH07220?

A: The ELFH07220 operates to a maximum of 105°C compared to the 1776140-7 maximum of 110°C. Applications requiring sustained operation above 105°C necessitate use of the primary part. Both components maintain full performance across the -40°C minimum temperature specification.

Q: How do the housing material differences affect component performance?

A: The 1776140-7 uses polyamide (nylon) housing while the ELFH07220 uses polybutylene terephthalate (PBT). Both materials achieve UL94 V-0 flammability rating. PBT provides enhanced chemical resistance and dimensional stability, while polyamide offers superior impact resistance. Material selection depends on environmental exposure conditions in the target application.

Q: What packaging considerations apply to these substitute parts?

A: The 1776140-7 is supplied in standard packaging with 994 pieces in stock. The ELFH07220 is supplied in tray packaging with 1066 pieces in stock. Packaging format affects handling, storage, and integration into assembly processes but does not impact electrical or mechanical performance.

Q: Are both parts compliant with current regulatory requirements?

A: Both the 1776140-7 and ELFH07220 are RoHS compliant, carry EAR99 export classification, and share identical HTSUS commodity code 8536.69.4040. Both components satisfy moisture sensitivity level 1 (unlimited) classification, confirming compatibility with standard storage and handling procedures without special environmental controls.
