TE Connectivity Erni 254587-E Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 254587-E is a shrouded surface mount rectangular connector header designed for board-to-board applications. This SMC series connector features 16 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing. The connector is actively manufactured and widely used in applications requiring reliable push-pull mated connections with solder termination on printed circuit boards.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate additional suppliers. All substitute parts listed maintain electrical and mechanical compatibility based on critical connector parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity Erni 254587-E are identified based on strict equivalence of critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must match or be compatible:

Critical Matching Parameters:

• Number of Positions: 16
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Contact Length - Mating: 0.157" (4.00mm)
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Contact Material: Copper Alloy
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature Range: -55°C to 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The HARTING 15110162601000 connector meets all critical parameters and is classified as a direct substitute. Minor variations in insulation height (0.260" versus 0.266") fall within acceptable mechanical tolerances for board-to-board header applications and do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity Erni 254587-E and HARTING 15110162601000 connectors are actively manufactured products with equivalent electrical and mechanical specifications. Selection between these parts is based on availability, supply chain requirements, and inventory management.

TE Connectivity Erni 254587-E is suitable for applications requiring the SMC series connector with established design history and TE Connectivity supply chain integration.

HARTING 15110162601000 is suitable as a direct substitute when TE Connectivity inventory is constrained or when HARTING supply chain relationships are preferred. The har-flex® series connector provides identical functional performance with compatible board-to-board mating characteristics.

Both parts comply with ROHS3 and REACH requirements, carry UL94 V-0 flammability ratings, and operate across the full -55°C to 125°C temperature range. Both parts feature MSL 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements.

The minor insulation height difference (0.266" versus 0.260") does not impact functional compatibility in standard board-to-board applications and falls within acceptable mechanical tolerances for connector header designs.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 15110162601000 be used as a direct replacement for the TE Connectivity Erni 254587-E?

A: Yes. Both connectors share identical pitch spacing (0.050" / 1.27mm), position count (16 positions in 2 rows), contact geometry, mating length (0.157" / 4.00mm), and electrical ratings. The connectors are mechanically and electrically compatible for board-to-board applications.

Q: What is the significance of the insulation height difference between the two parts?

A: The TE Connectivity part specifies 0.266" (6.75mm) insulation height while the HARTING part specifies 0.260" (6.60mm). This 0.006" (0.15mm) difference is within standard mechanical tolerances for connector headers and does not affect mating performance or board-level compatibility.

Q: Are both connectors suitable for the same operating temperature range?

A: Yes. Both the TE Connectivity Erni 254587-E and HARTING 15110162601000 operate across -55°C to 125°C, making them suitable for identical thermal environments.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both connectors are ROHS3 compliant, REACH unaffected, carry UL94 V-0 flammability ratings, and feature MSL 1 (Unlimited) moisture sensitivity classification. Both are classified under ECCN EAR99 and HTSUS code 8536.69.4040.

Q: What is the current rating for these connectors?

A: The TE Connectivity Erni 254587-E specifies 1.7A per contact. The HARTING 15110162601000 does not specify a current rating in the provided data; however, the identical contact geometry and copper alloy material indicate equivalent current-carrying capability.

Q: Are these connectors suitable for automated assembly?

A: Yes. Both connectors feature pick and place compatibility and solder retention characteristics, making them suitable for surface mount assembly processes.

Q: What is the difference between the SMC and har-flex® series designations?

A: SMC and har-flex® are manufacturer-specific series names for their respective connector product lines. Both series employ identical electrical and mechanical specifications for this 16-position, 1.27mm pitch header connector.
