TE Connectivity 1452931-3 Rectangular Connector Housing – Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1452931-3 is a 76-position rectangular connector receptacle housing designed for 3.00mm pitch applications. This component functions as a female socket housing with slide lock fastening, configured in a 4-row arrangement with 0.152" row spacing. The housing accommodates crimp-terminated contacts and is manufactured from glass-filled polyamide (PA66/Nylon 6/6) material.

The 1452931-3 maintains Active product status and is RoHS Compliant with MSL Level 1 (Unlimited moisture sensitivity). Substitute parts are identified to address inventory availability, packaging requirements, and compliance variations while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1452931-3 are qualified based on matching electrical and mechanical parameters that define functional interchangeability. The following parameters establish substitution validity:

Critical Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 76
• Pitch: 0.118" (3.00mm)
• Number of Rows: 4
• Row Spacing: 0.152" (3.85mm)
• Mounting Type: Free Hanging (In-Line), Right Angle
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Color: Black
• Features: Slide Lock

All identified substitute parts maintain these critical parameters. Variations in packaging format, RoHS certification generation, and inventory levels do not affect functional compatibility. The base product number may differ (1452931 versus 1452995) while maintaining identical dimensional and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Part 9-1452931-9 (Bulk Packaging Variant)

The 9-1452931-9 is a direct parametric equivalent to the 1452931-3, differentiated by bulk packaging format and ROHS3 compliance certification. This part maintains all critical electrical and mechanical specifications. The ROHS3 designation represents an updated compliance generation while maintaining functional equivalence. Insulation material specification is not provided for this variant; however, all other dimensional and electrical parameters are identical. This part is suitable for applications where bulk packaging is acceptable and ROHS3 compliance is required.

Part 9-1452995-9 (Alternative Base Product Number)

The 9-1452995-9 maintains identical electrical and mechanical specifications to the 1452931-3, including insulation material composition (Polyamide PA66/Nylon 6/6, Glass Filled), RoHS compliance, and MSL Level 1 rating. The primary distinction is the base product number (1452995 versus 1452931), which does not affect functional compatibility. This part is suitable for direct substitution where inventory of the original part number is unavailable.

Both substitute parts are Active status products from TE Connectivity AMP Connectors with confirmed inventory availability. Selection between substitutes depends on packaging requirements and compliance certification preferences.

Frequently Asked Questions (FAQ)

Q: Can 9-1452931-9 be used as a direct replacement for 1452931-3?

A: Yes. The 9-1452931-9 maintains all critical electrical and mechanical parameters: 76 positions, 3.00mm pitch, 4-row configuration, crimp termination, and slide lock fastening. The primary difference is packaging format (bulk versus standard) and ROHS3 compliance certification. Functional compatibility is confirmed.

Q: What is the significance of the different base product numbers (1452931 versus 1452995)?

A: The base product number variation does not indicate functional differences. Both 1452931-3 and 9-1452995-9 share identical dimensional specifications, contact configuration, and electrical characteristics. The different base numbers reflect TE Connectivity's internal product classification but do not affect interchangeability.

Q: Is the unspecified insulation material in 9-1452931-9 a compatibility concern?

A: No. The 9-1452931-9 is confirmed as a parametric equivalent with all critical specifications matching the 1452931-3. While insulation material is not documented for this variant, all other parameters—including pitch, position count, row configuration, and termination method—are identical. The part is suitable for direct substitution.

Q: How does packaging format affect part selection?

A: Packaging format (bulk versus standard) affects handling, storage, and ordering quantities but does not impact electrical or mechanical performance. The 9-1452931-9 is supplied in bulk packaging, which may be advantageous for high-volume applications or inventory consolidation. Selection depends on procurement and logistics requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The 1452931-3 and 9-1452995-9 are RoHS Compliant. The 9-1452931-9 is ROHS3 Compliant, representing a more recent compliance certification generation. Both compliance levels are acceptable for applications requiring RoHS adherence.

Q: What does MSL Level 1 (Unlimited) indicate?

A: MSL Level 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. This applies to the 1452931-3 and 9-1452995-9. The 9-1452931-9 lists MSL as Not Applicable, which does not affect functional compatibility.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All three parts maintain identical connector type (receptacle), contact type (female socket), position count (76), pitch (3.00mm), row configuration (4 rows), mounting type (free hanging/right angle), and fastening mechanism (latch holder with slide lock). Direct substitution is supported without design modification.
