PS-20B2-1 Equivalent & Substitute Parts

Part Overview

The PS-20B2-1 is a 20-position ribbon cable connector manufactured by JAE Electronics, designed for through-hole mounting applications with IDC (Insulation Displacement Connector) termination. This connector features a 0.050" (1.27mm) cable pitch and 0.200" (5.08mm) board-side pitch, accommodating 28 AWG wire gauge with gold-plated contacts and feed-through capability.

The PS-20B2-1 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or repair requirements for systems utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS-20B2-1 is determined by strict equivalence across the following critical parameters:

• Connector Type: Ribbon Cable (IDC termination method)
• Position Count: 20 positions
• Cable Pitch: 0.050" (1.27mm)
• Board-Side Pitch: 0.200" (5.08mm)
• Row Configuration: 4 rows with 0.100" (2.54mm) spacing
• Mounting Method: Through Hole
• Termination Standard: IDC
• Wire Gauge Compatibility: 28 AWG or compatible range (28-30 AWG)
• Moisture Sensitivity: MSL 1 or equivalent

The CWR-142-20-0203 meets all substitution criteria. It maintains identical mechanical and electrical pitch specifications, supports the same 20-position, 4-row configuration, and accepts compatible wire gauges (28-30 AWG, stranded or solid). Both connectors feature feed-through capability and unlimited moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

The CWR-142-20-0203 is the qualified substitute for the PS-20B2-1. Selection is based on the following factors:

Mechanical Compatibility: Both connectors share identical pitch specifications (0.050" cable pitch, 0.200" board-side pitch) and row configuration (4 rows, 0.100" spacing), ensuring direct mechanical interchangeability on existing PCB layouts.

Electrical Compatibility: Both connectors support 20-position IDC ribbon cable termination with feed-through capability. The CWR-142-20-0203 accepts 28-30 AWG wire (stranded or solid), which encompasses the PS-20B2-1 specification of 28 AWG solid wire.

Product Status: The CWR-142-20-0203 maintains active production status with 7552 units in stock, providing reliable long-term availability compared to the obsolete PS-20B2-1.

Compliance: Both connectors carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The CWR-142-20-0203 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Contact Finish Difference: The PS-20B2-1 features gold-plated contacts, while the CWR-142-20-0203 uses tin plating. Both finishes are suitable for IDC ribbon cable applications; contact finish selection depends on specific corrosion resistance or signal integrity requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can the CWR-142-20-0203 directly replace the PS-20B2-1 on existing PCBs?

A: Yes. Both connectors share identical mechanical specifications: 20 positions, 0.050" cable pitch, 0.200" board-side pitch, 4-row configuration with 0.100" row spacing, and through-hole mounting. No PCB redesign is required.

Q: What is the difference in wire gauge compatibility?

A: The PS-20B2-1 is specified for 28 AWG wire. The CWR-142-20-0203 accepts 28-30 AWG wire in both stranded and solid configurations. This broader specification ensures compatibility with the original 28 AWG requirement while supporting additional wire gauge options.

Q: Does the contact finish difference affect performance?

A: The PS-20B2-1 uses gold plating; the CWR-142-20-0203 uses tin plating. Both finishes are appropriate for IDC ribbon cable connectors. Gold plating offers enhanced corrosion resistance in high-humidity or corrosive environments. Tin plating is standard for general-purpose applications. Selection depends on environmental exposure and signal integrity requirements specific to the application.

Q: Are there packaging differences between these connectors?

A: The PS-20B2-1 packaging information is not specified in available data. The CWR-142-20-0203 is supplied in bulk packaging. Confirm packaging requirements with your procurement or assembly team.

Q: What is the availability status of each connector?

A: The PS-20B2-1 is obsolete with 1054 units listed as new original stock. The CWR-142-20-0203 is active production with 7552 units in stock, providing superior long-term availability for ongoing production requirements.

Q: Are both connectors moisture sensitive?

A: No. Both connectors carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard storage and handling practices apply.
