Substitute Part Grouping Explanation

Substitute parts for the ESW-134-44-L-D are identified within the ESW series based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Identical number of positions: 68
• Identical pitch spacing: 0.100" (2.54mm)
• Identical row configuration: 2 rows with 0.100" (2.54mm) row spacing
• Identical connector type: Elevated Socket
• Identical contact type: Forked
• Identical mounting and termination: Through Hole, Solder
• Identical electrical ratings: 5.2A per contact, 550VAC
• Identical operating temperature range: -55°C ~ 125°C
• Identical contact finishes: Gold (mating), Tin (post)
• Identical insulation material: Liquid Crystal Polymer (LCP)
• Identical flammability rating: UL94 V-0
• Identical compliance: ROHS3 Compliant
• Active product status

The ESW-134-69-L-D meets all these criteria and is classified as a manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ESW-134-44-L-D and ESW-134-69-L-D are Active status products manufactured by Samtec Inc. and maintain full ROHS3 compliance. The parts are electrically and mechanically equivalent across all specified parameters. Selection between these parts should be based on inventory availability and lead time requirements, as both meet identical electrical performance, thermal operating range, and regulatory compliance standards. Both parts carry UL94 V-0 flammability certification and are suitable for the same board-to-board connector applications.

Frequently Asked Questions (FAQ)

Q: Are ESW-134-44-L-D and ESW-134-69-L-D fully interchangeable?

A: Yes. Both parts are identical in electrical ratings (5.2A per contact, 550VAC), mechanical configuration (68 positions, 0.100" pitch, 2 rows), contact materials and finishes, operating temperature range (-55°C ~ 125°C), and regulatory compliance (ROHS3, UL94 V-0). They are direct substitutes within the ESW series.

Q: What determines substitution eligibility for ESW-134 connectors?

A: Substitution is based on matching position count, pitch spacing, row configuration, connector type (Elevated Socket), contact type (Forked), mounting method (Through Hole), termination type (Solder), electrical ratings, operating temperature, contact finishes, insulation material, and compliance certifications.

Q: Can I use these connectors in applications requiring different voltage or current ratings?

A: No. Both parts are rated for 5.2A per contact and 550VAC. Applications requiring different electrical ratings require different connector models.

Q: Are there packaging differences between these substitute parts?

A: Both parts are supplied in Bulk packaging. Packaging format is identical.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -55°C to 125°C, suitable for industrial and extended temperature applications.
