TE Connectivity AMP Connectors 144477-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 144477-1 is a 7-position rectangular connector receptacle housing designed for applications requiring free-hanging in-line mounting with crimp contact termination. This component belongs to the Junior Power Timer series and is classified as an active product with full RoHS compliance. The housing accommodates female socket contacts at a 0.197" (5.00mm) pitch and operates across a temperature range of -40°C to 100°C. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific application requirements necessitate alternative configurations such as different color specifications or extended operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across critical electrical and mechanical parameters. The substitute part TE Connectivity AMP Connectors 928343-7 qualifies as a parametric equivalent based on the following matching criteria:

Matching Parameters (Substitution Basis):

• Connector type: Receptacle
• Contact type: Female Socket
• Number of positions: 7
• Pitch: 0.197" (5.00mm)
• Number of rows: 1
• Mounting type: Free Hanging (In-Line)
• Contact termination: Crimp
• Insulation material: Polyamide (PA66), Nylon 6/6
• Moisture sensitivity level: 1 (Unlimited)
• HTSUS classification: 8536.69.8000

Differing Parameters (Non-Critical Variations):

• Housing color: Black (144477-1) versus Natural (928343-7)
• Series designation: Junior Power Timer versus Standard Timer
• Operating temperature upper limit: 100°C versus 110°C
• RoHS certification version: RoHS Compliant versus ROHS3 Compliant
• Packaging: Not specified versus Bulk

These variations do not affect mechanical or electrical interchangeability for applications within the overlapping operating temperature range of -40°C to 100°C.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part 144477-1 and substitute part 928343-7 are active products with confirmed RoHS compliance status, ensuring regulatory conformance for applications subject to hazardous substance restrictions. The substitute part 928343-7 provides an extended operating temperature upper limit of 110°C compared to the primary part's 100°C specification, offering enhanced thermal performance for applications approaching the upper temperature boundary.

Selection between these parts should be based on the following criteria:

Select 144477-1 when:

• Black housing color is a functional or aesthetic requirement
• Operating temperature does not exceed 100°C
• Junior Power Timer series designation is specified in design documentation

Select 928343-7 when:

• Natural housing color is acceptable
• Operating temperature range extends to 110°C
• ROHS3 compliance certification is required
• Standard Timer series compatibility is acceptable
• Bulk packaging format is preferred for high-volume applications

Both parts maintain identical electrical and mechanical characteristics within the overlapping operating temperature range of -40°C to 100°C, ensuring functional interchangeability for applications within this envelope.

Frequently Asked Questions (FAQ)

Q: Are 144477-1 and 928343-7 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including 7-position configuration, 0.197" (5.00mm) pitch, single-row layout, and free-hanging in-line mounting type. The housings accept the same crimp-terminated female socket contacts.

Q: What is the primary difference between these two parts?

A: The primary differences are housing color (Black versus Natural) and operating temperature upper limit (100°C versus 110°C). These are non-functional variations that do not affect electrical or mechanical interchangeability within the overlapping temperature range.

Q: Can I use 928343-7 in an application designed for 144477-1?

A: Yes, provided the application does not have specific requirements for black housing color. The substitute part meets or exceeds all electrical and mechanical specifications of the primary part within the -40°C to 100°C operating range.

Q: Does the color difference affect connector performance?

A: No. Housing color is a cosmetic specification that does not impact electrical performance, mechanical fit, or thermal characteristics. Both black and natural polyamide housings provide identical insulation properties and contact retention.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and does not require special moisture-controlled storage or handling procedures. Both parts carry this classification.

Q: Are both parts RoHS compliant?

A: Yes. The primary part 144477-1 is RoHS Compliant, and the substitute part 928343-7 is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions. ROHS3 represents a newer certification standard.

Q: What is the difference between packaging specifications?

A: The primary part 144477-1 has unspecified packaging, while 928343-7 is supplied in Bulk packaging format. Bulk packaging typically accommodates higher-volume orders without individual component packaging.

Q: Can these housings be used without contacts?

A: Both part numbers are housings only and do not include contacts. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.

Q: Which part should I select for a new design?

A: For new designs, either part is acceptable based on application requirements. If operating temperature may approach or exceed 100°C, 928343-7 provides additional thermal margin. If black housing is a design requirement, 144477-1 is the appropriate selection.
