Key Parameters

Substitute Part Grouping Explanation

Substitution within this product family is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for parts to be considered direct substitutes:

• Number of Positions: 21
• Pitch: 0.197" (5.00mm)
• Number of Rows: 3
• Row Spacing: 0.217" (5.51mm)
• Connector Type: Receptacle
• Contact Type: Female Socket
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Insulation Material: Polybutylene Terephthalate (PBT), Glass Filled
• Operating Temperature Range: -40°C to 120°C
• Moisture Sensitivity Level: 1 (Unlimited)
• Series: LEAVYSEAL
• Base Product Number: 1534127

The substitute parts 1-1534127-1 and 2-1534127-1 maintain complete parametric equivalence to the main part 4-1534127-1. The only variation between these parts is the housing color (Violet, Black, or Natural), which does not affect electrical performance or mechanical compatibility. All three parts are manufactured by TE Connectivity, share the same base product number, and are classified within the same rectangular connector category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—4-1534127-1, 1-1534127-1, and 2-1534127-1—are Active products manufactured by TE Connectivity and maintain full compliance with RoHS regulations. The main part 4-1534127-1 carries RoHS Compliant status, while the substitute parts 1-1534127-1 and 2-1534127-1 carry ROHS3 Compliant status, indicating enhanced regulatory alignment.

Selection between these parts should be based on:

1. Housing color requirements for your application or assembly documentation
2. Current inventory availability and lead time considerations
3. Regulatory compliance requirements specific to your end-use application

The substitute part 2-1534127-1 (Natural color) currently maintains the highest inventory level at 2300 pieces, followed by 1-1534127-1 (Black) at 1189 pieces, and 4-1534127-1 (Violet) at 1115 pieces. All parts are suitable for immediate deployment in production environments.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1-1534127-1 or 2-1534127-1 for 4-1534127-1 in my connector assembly?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications, including position count, pitch, row configuration, termination method, and operating temperature range. The only difference is housing color, which does not affect functional compatibility.

Q: Does housing color affect electrical performance?

A: No. Housing color is a cosmetic and identification feature only. All three parts use the same PBT glass-filled insulation material and deliver identical electrical performance across the specified operating temperature range of -40°C to 120°C.

Q: Are there any compatibility issues with existing connector contacts?

A: No. All three parts are designed for crimp termination with the same contact specifications. Contacts are not included with any of these housings and must be sourced separately. The 21-position, 5.00mm pitch configuration is consistent across all variants.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: Both designations indicate compliance with RoHS (Restriction of Hazardous Substances) regulations. ROHS3 represents the current version of the directive. Both statuses confirm that the parts meet hazardous substance restrictions and are suitable for regulated applications.

Q: Can I mix these parts in the same production batch?

A: Yes. Since all three parts are parametrically equivalent and share the same base product number (1534127), they can be used interchangeably within the same assembly design. Color differentiation may be useful for internal tracking or visual identification purposes.

Q: What is the Moisture Sensitivity Level (MSL) 1 rating?

A: MSL 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. These parts do not require dry-pack storage or baking procedures prior to assembly.

Q: Are these parts available in other configurations?

A: The information provided covers only the 21-position, 5.00mm pitch variants within the LEAVYSEAL series. Other position counts or pitch configurations would require separate part number designations.
