PS-26B2-1 Equivalent & Substitute Parts

Part Overview

The PS-26B2-1 is a 26-position ribbon cable connector manufactured by JAE Electronics, designed for through-hole mounting applications. This connector features IDC (Insulation Displacement Contact) termination with 28 AWG wire gauge capability and a feed-through design. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS-26B2-1 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Ribbon cable connector with identical 26-position, 4-row arrangement
• Pitch Specifications: Cable pitch of 0.050" (1.27mm) and board-side pitch of 0.200" (5.08mm) must match exactly
• Mounting & Termination: Through-hole mounting with IDC termination method
• Electrical Compatibility: Wire gauge range must accommodate 28 AWG minimum
• Physical Features: Feed-through design and row spacing of 0.100" (2.54mm)
• Environmental Rating: MSL 1 (Unlimited) moisture sensitivity

The substitute part 1-6437006-8 meets all these criteria, with the additional capability of accepting 28-30 AWG wire in both stranded and solid configurations.

Parameter Comparison

Engineering Selection Recommendations

The 1-6437006-8 from TE Connectivity AMP Connectors is a direct functional substitute for the obsolete PS-26B2-1. All critical mechanical and electrical parameters align, including connector configuration, pitch specifications, mounting method, and termination type.

The substitute part offers the following advantages:

• Active product status with ongoing manufacturing and availability
• RoHS compliance certification
• Extended wire gauge compatibility (28-30 AWG) accommodating both stranded and solid conductors
• Tin contact finish suitable for IDC ribbon cable applications
• Identical MSL rating for environmental performance

The contact finish difference (gold versus tin) does not affect functional compatibility in IDC termination applications, where contact pressure and displacement characteristics are the primary performance factors.

Frequently Asked Questions (FAQ)

Q: Can the 1-6437006-8 directly replace the PS-26B2-1 in existing designs?

A: Yes. Both connectors share identical pitch specifications, position count, row configuration, and mounting method. The mechanical and electrical interfaces are equivalent.

Q: What is the significance of the wire gauge difference (28 AWG versus 28-30 AWG)?

A: The PS-26B2-1 specifies 28 AWG wire. The 1-6437006-8 accepts 28-30 AWG in both stranded and solid configurations. This broader specification is compatible with 28 AWG applications and provides additional flexibility for future designs.

Q: Does the contact finish difference affect performance?

A: No. In IDC ribbon cable connectors, contact finish (gold or tin) does not affect the displacement and retention characteristics that determine connector performance. Both finishes are suitable for this application category.

Q: Is the substitute part currently available?

A: Yes. The 1-6437006-8 has active product status with 721 pieces in stock, compared to the obsolete PS-26B2-1.

Q: Are there compliance differences between the two parts?

A: The 1-6437006-8 carries RoHS compliance certification. Both parts share identical MSL ratings and ECCN/HTSUS classifications.

Q: What packaging format is the substitute supplied in?

A: The 1-6437006-8 is supplied in tray packaging, suitable for automated assembly and component handling.
