Keystone Electronics 1500 WTB Tin Terminal Connector - Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 1500 is a through-board wire terminal connector featuring tin-plated beryllium copper contacts. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and design requirements. The WTB (Wire Terminal Board) configuration provides direct board-level termination for wire connections in electronic assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Keystone Electronics 1500 is determined by the following critical parameters:

• Terminal Type: Must be through-board configuration for direct PCB mounting compatibility
• Hole Diameter Tolerance: Substitute hole diameter range must accommodate or overlap with 0.062" (1.57mm) specification
• Contact Finish: Tin plating required for solder compatibility and corrosion resistance
• Overall Length: Physical envelope constraints for board-level integration
• Compliance Standards: RoHS3 compliance and MSL rating must meet or exceed original specification

The TE Connectivity AMP Connectors 172782-5 qualifies as a manufacturer-recommended substitute based on these parameters. The hole diameter range of 0.047" to 0.063" (1.19mm to 1.60mm) encompasses the original 0.062" specification, and the tin contact finish maintains electrical and environmental performance equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 172782-5 is the active equivalent for the obsolete Keystone Electronics 1500. Selection of this substitute is supported by:

• Compliance Alignment: Both components maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental performance equivalence
• Active Product Status: The TE Connectivity part is in active production, providing long-term supply chain stability and availability
• Mechanical Compatibility: The hole diameter tolerance range of the substitute encompasses the original specification, permitting direct PCB footprint compatibility
• Electrical Performance: Tin contact finish on both components ensures equivalent solder joint reliability and corrosion resistance

The 0.040" (1.02mm) reduction in overall length of the substitute part should be evaluated within specific board-level integration constraints, though this difference is within typical component tolerance ranges for through-board terminal applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 172782-5 be used as a direct replacement for the Keystone 1500?

A: Yes, the TE Connectivity 172782-5 qualifies as a direct substitute based on through-board terminal type, compatible hole diameter tolerance, and equivalent tin contact finish. The 0.040" length difference should be verified against specific board assembly requirements.

Q: What is the significance of the hole diameter tolerance range on the substitute part?

A: The TE Connectivity 172782-5 specifies a hole diameter range of 0.047" to 0.063" (1.19mm to 1.60mm). The original Keystone 1500 hole diameter of 0.062" falls within this range, confirming mechanical compatibility for PCB mounting.

Q: Are there compliance differences between the original and substitute parts?

A: No. Both the Keystone 1500 and TE Connectivity 172782-5 maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring equivalent regulatory and environmental performance.

Q: What is the wire gauge specification for the substitute part?

A: The TE Connectivity 172782-5 is rated for 22-26 AWG wire gauges. The original Keystone 1500 does not specify wire gauge in the provided data. Verify that intended wire gauges fall within the 22-26 AWG range for optimal contact engagement.

Q: Why is the Keystone 1500 classified as obsolete?

A: The Keystone 1500 is no longer in active production. The TE Connectivity 172782-5 represents the active equivalent in the Mini Amp-In series, providing continued availability and supply chain support.
