Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across electrical and mechanical parameters. The substitute part 1-1534127-1 qualifies as a parametric equivalent based on the following criteria:

Critical Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (21)
• Pitch specification (0.197" / 5.00mm)
• Row configuration (3 rows)
• Row spacing (0.217" / 5.51mm)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Insulation material (PBT, Glass Filled)
• Operating temperature range (-40°C ~ 120°C)
• Series designation (LEAVYSEAL)
• Compliance certifications (ROHS3, MSL Level 1)

The only variable parameter between the main part and substitute is the housing color (Natural versus Black). This color variation does not affect electrical performance, mechanical compatibility, or thermal characteristics. Both parts share identical base product number 1534127, confirming their functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the main part number 2-1534127-1 and substitute part number 1-1534127-1 are Active products with identical compliance certifications and electrical specifications. Selection between these parts should be based on the following factors:

Availability and Inventory: The main part (2-1534127-1) has 2300 pieces in stock, while the substitute (1-1534127-1) has 1189 pieces available. Component selection should prioritize inventory availability for project timelines.

Color Specification: The main part features Natural housing color, while the substitute provides Black housing. Color selection depends on application requirements, assembly aesthetics, or system integration specifications. Both colors are functionally equivalent in electrical and mechanical performance.

Compliance Status: Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming suitability for standard storage and handling without moisture sensitivity concerns.

Base Product Equivalence: Both parts share base product number 1534127, confirming they are manufactured to identical specifications within the LEAVYSEAL series and are fully interchangeable from an electrical and mechanical standpoint.

Frequently Asked Questions (FAQ)

Q: Can part 1-1534127-1 be used as a direct replacement for 2-1534127-1?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications. The only difference is housing color (Black versus Natural). Direct substitution is valid when color requirements do not restrict component selection.

Q: What determines whether these parts are interchangeable?

A: Interchangeability is determined by matching specifications across connector type, contact type, position count, pitch, row configuration, row spacing, mounting type, termination method, insulation material, and operating temperature range. Both parts match on all these parameters.

Q: Does the color difference affect connector performance?

A: No. Housing color is a cosmetic parameter that does not affect electrical conductivity, mechanical fit, thermal performance, or environmental resistance. Both Natural and Black housings provide identical functional performance.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 120°C. No thermal performance differences exist between the two part numbers.

Q: What is the significance of the LEAVYSEAL series designation?

A: The LEAVYSEAL series designation indicates both parts belong to the same product family with standardized specifications. This series classification confirms compatibility and interchangeability within the rectangular connector housing category.

Q: Do both parts require the same contact specifications?

A: Yes. Both housings are designed for 21 crimp-terminated female socket contacts with 5.00mm pitch spacing. Contact selection and specifications remain identical regardless of which housing part number is used.

Q: What does MSL Level 1 mean for storage and handling?

A: MSL Level 1 indicates unlimited shelf life under standard storage conditions. Both parts do not require special moisture-controlled storage and can be handled using standard component management practices.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain identical RoHS3 compliance status and carry the same regulatory certifications. No compliance restrictions apply to substitution between these part numbers.
