Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings within the AMPSEAL 16 series is determined by electrical and mechanical parameter equivalence. The substitute parts 776488-1, 776488-2, 776488-3, and 776536-1 are classified as parametric equivalents to the primary part 776488-4 based on the following critical parameters:

Electrical Parameters:

• Connector type (Receptacle)
• Contact type (Male Pin)
• Number of positions (4)
• Pitch specification (0.177" / 4.50mm)
• Row configuration (2 rows)
• Row spacing (0.209" / 5.30mm)

Mechanical Parameters:

• Mounting type (Free Hanging / In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Locking Ramp)
• Housing color (Black)
• Insulation material (Thermoplastic, Glass Filled)

Environmental & Compliance Parameters:

• Operating temperature range (-40°C ~ 125°C)
• RoHS3 compliance status
• Moisture sensitivity level (MSL 1)
• ECCN classification (EAR99)
• HTSUS code (8536.69.8000)

All substitute parts maintain identical specifications across these parameters, confirming direct interchangeability within the AMPSEAL 16 connector series.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 776488-1, 776488-2, 776488-3, and 776536-1 directly interchangeable with 776488-4?

A: Yes. All substitute parts are parametric equivalents with identical electrical and mechanical specifications, including connector type, number of positions, pitch, row configuration, mounting type, contact termination, and fastening mechanism. They are suitable for direct substitution in applications requiring AMPSEAL 16 series 4-position receptacle housings.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence in the following parameters: connector type (Receptacle), contact type (Male Pin), number of positions (4), pitch (0.177" / 4.50mm), row configuration (2 rows), row spacing (0.209" / 5.30mm), mounting type (Free Hanging / In-Line), contact termination (Crimp), fastening type (Locking Ramp), insulation material (Thermoplastic, Glass Filled), and operating temperature range (-40°C ~ 125°C).

Q: Do all substitute parts meet the same compliance requirements as the primary part?

A: Yes. All parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level. The substitute parts carry REACH Unaffected status, confirming regulatory compliance for applications subject to REACH requirements.

Q: Are contacts included with these connector housings?

A: No. All parts in this series are supplied as housings only. Contacts are not included and must be sourced separately.

Q: What is the difference between part numbers 776488-4 and 776536-1?

A: Both parts are parametric equivalents within the AMPSEAL 16 series with identical electrical and mechanical specifications. The difference lies in the base product number designation (776488 versus 776536), which may reflect different manufacturing batches or internal product line classifications. All functional parameters remain identical.

Q: Can these connector housings be used in applications with operating temperatures outside the -40°C to 125°C range?

A: No. All parts in this series are rated for operation within the -40°C to 125°C temperature range. Applications requiring operation outside this range require alternative connector housing designs.

Q: What packaging format is used for these parts?

A: All parts are supplied in Bulk packaging format.
