TE Connectivity 638245-2 Rectangular Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 638245-2 is a 4-position rectangular connector receptacle housing from the Junior Power Timer series. This component serves as the female socket housing for crimp-terminated connections with a 6.00mm pitch. The part is actively manufactured and maintained in production status. Identification of equivalent substitute parts is necessary to ensure supply chain continuity, optimize inventory management, and provide alternative sourcing options when the primary part number becomes unavailable or when bulk purchasing requirements necessitate alternative stock locations.

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across all critical electrical and mechanical parameters. The 638245-2 and its substitute part 638245-1 are classified as parametric equivalents based on the following matching criteria:

Critical Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (4)
• Pitch specification (0.236" / 6.00mm)
• Number of rows (1)
• Mounting configuration (Free Hanging In-Line)
• Contact termination method (Crimp)
• Housing color (Black)
• Sealed retainer features
• Insulation material composition (PBT, Glass Filled)
• Operating temperature range (-40°C to 125°C)
• RoHS compliance status
• MSL rating (1 - Unlimited)
• Series designation (Junior Power Timer)

Both parts originate from the same manufacturer (TE Connectivity AMP Connectors) and share an identical base product number (638245), differing only in the suffix designation. This structural relationship confirms their functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the 638245-2 and 638245-1 are active production parts manufactured by TE Connectivity AMP Connectors and maintain full RoHS compliance certification. The parts are functionally equivalent across all specified electrical and mechanical parameters, including connector architecture, contact configuration, pitch specification, termination method, temperature rating, and moisture sensitivity classification.

Selection between these two part numbers should be based on inventory availability and supply chain requirements. The 638245-1 currently maintains higher inventory levels (1180 pieces) compared to the 638245-2 (866 pieces), which may influence procurement decisions for high-volume applications or extended lead-time mitigation strategies.

Both parts are suitable for applications requiring 4-position rectangular connectors with 6.00mm pitch spacing, crimp termination, and sealed housing construction within the -40°C to 125°C operating envelope. The interchangeability of these parts is confirmed by their identical parametric specifications and shared base product designation within the Junior Power Timer series.

Frequently Asked Questions (FAQ)

Q: Are the 638245-2 and 638245-1 directly interchangeable?

A: Yes. Both parts are parametric equivalents with identical specifications across all critical electrical and mechanical parameters, including connector type, position count, pitch, mounting configuration, termination method, insulation material, temperature rating, and compliance certifications.

Q: What is the difference between the 638245-2 and 638245-1 part numbers?

A: The suffix designation (-2 versus -1) distinguishes these as separate part number variants within the same product family. All functional and electrical specifications remain identical. The parts share the same base product number (638245) and series designation (Junior Power Timer).

Q: Can I substitute 638245-1 for 638245-2 in existing designs?

A: Yes. The parametric equivalence of these parts permits direct substitution without design modification. Both parts maintain identical connector architecture, contact configuration, pitch spacing, and performance characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both the 638245-2 and 638245-1 are RoHS compliant and carry MSL rating 1 (Unlimited moisture sensitivity level).

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

A: Both parts operate within the -40°C to 125°C temperature range, suitable for industrial and commercial applications requiring extended thermal performance.

Q: Are contacts included with these housing parts?

A: No. Both the 638245-2 and 638245-1 are housing components only. Contacts are not included and must be sourced separately as crimp-terminated components compatible with the 6.00mm pitch specification.

Q: What mounting configuration do these connectors support?

A: Both parts are configured for free hanging in-line mounting, suitable for applications requiring flexible connector positioning without fixed panel mounting requirements.

Q: What insulation material is used in these housings?

A: Both parts utilize polybutylene terephthalate (PBT) with glass filling, providing mechanical strength, thermal stability, and electrical insulation properties suitable for the specified operating temperature range.
