316-87-111-41-011101 Rectangular Connector Socket - Equivalent & Substitute Parts

Part Overview

The 316-87-111-41-011101 is an 11-position socket connector manufactured by Preci-Dip, designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts, tin-plated posts, and operates across the industrial temperature range of -55°C to 125°C. The product maintains Active status and is RoHS3 compliant.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits alternative connector geometries that maintain functional compatibility within the specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

The ESS-111-T-05 manufactured by Samtec Inc. qualifies as a functional substitute for the 316-87-111-41-011101 based on the following alignment of critical parameters:

Matching Parameters:

11-position socket connector configuration
0.100" (2.54mm) mating pitch
Female socket contact type
Board-to-board style
Through-hole solder termination
Gold-plated mating contacts
Push-pull fastening mechanism
Operating temperature range: -55°C ~ 125°C
UL94 V-0 flammability rating
Beryllium copper contact material
RoHS3 compliance
ECCN EAR99 classification

Geometric Variation: The ESS-111-T-05 is classified as an elevated socket connector with an insulation height of 0.500" (12.70mm) compared to the 0.709" (18.00mm) of the primary part. This dimensional difference requires PCB layout verification to ensure clearance compatibility in the target application.

Engineering Selection Recommendations

Primary Part Selection (316-87-111-41-011101): Select the Preci-Dip 316-87-111-41-011101 when the application requires the specified insulation height of 0.709" (18.00mm) and the 3A current rating is a documented requirement. This part maintains Active product status with 718 units in stock.

Substitute Part Selection (ESS-111-T-05): The Samtec ESS-111-T-05 is electrically and mechanically compatible when PCB layout accommodates the reduced insulation height of 0.500" (12.70mm) and the extended contact post length of 0.173" (4.40mm). Both parts maintain identical operating temperature ranges, UL94 V-0 flammability compliance, and RoHS3 certification. The ESS-111-T-05 offers 859 units in stock. The substitute part uses Liquid Crystal Polymer (LCP) insulation material versus the glass-filled polyester of the primary part, which may affect mechanical properties in specific environmental conditions.

Compliance Verification: Both parts carry ECCN EAR99 classification and HTSUS code 8536.69.4040, ensuring equivalent regulatory treatment for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can the ESS-111-T-05 be used as a direct drop-in replacement for the 316-87-111-41-011101?

A: Electrical compatibility is confirmed across all mating and termination parameters. Mechanical compatibility requires verification of PCB clearance due to the 0.209" (5.30mm) reduction in insulation height and the 0.047" (1.20mm) increase in contact post length. Layout review is mandatory before substitution.

Q: What is the significance of the insulation material difference between PCT/Polyester and LCP?

A: Both materials meet UL94 V-0 flammability requirements. Liquid Crystal Polymer (LCP) offers superior dimensional stability and lower moisture absorption compared to glass-filled polyester. Material selection should align with the application's thermal cycling and humidity exposure profile.

Q: Are the gold plating specifications equivalent between the two parts?

A: The primary part specifies flash gold plating on mating contacts. The substitute part specifies 10.0µin (0.25µm) gold plating. Both provide corrosion resistance and electrical conductivity suitable for 0.100" pitch connectors. The substitute's specified thickness provides measurable plating documentation.

Q: What is the impact of the current rating specification difference?

A: The primary part specifies 3A current rating. The substitute part does not provide a current rating specification in the available data. Applications requiring documented 3A current capacity should reference the primary part or obtain current rating documentation from Samtec for the ESS-111-T-05.

Q: Are both parts suitable for the same operating temperature applications?

A: Yes. Both parts operate across -55°C to 125°C, supporting industrial and extended commercial temperature range applications without thermal derating.

Q: What packaging considerations apply to these parts?

A: Both parts are supplied in bulk packaging. The primary part has 718 units in stock; the substitute has 859 units available. Procurement lead times and minimum order quantities should be verified with the respective manufacturers or authorized distributors.
