Molex 0455870002 Equivalent & Substitute Parts

Part Overview

The Molex 0455870002 is an 8-position rectangular connector receptacle housing with 0.165" (4.20mm) pitch, designed for Mini-Fit Jr 45587 series applications. This component features a black polyamide (PA) nylon insulation material, crimp contact termination, and latch lock fastening. The part operates across a temperature range of -40°C to 105°C and is classified as Obsolete. Due to its obsolete status, equivalent substitute parts from active product lines are necessary to maintain design continuity and ensure ongoing component availability for new production and field service applications.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0455870002 is determined by strict parametric equivalence across the following critical dimensions:

Mandatory Matching Parameters:

Connector Type: Receptacle
Contact Type: Female Socket
Number of Positions: 8
Pitch: 0.165" (4.20mm)
Number of Rows: 2
Row Spacing: 0.165" (4.20mm)
Mounting Type: Free Hanging (In-Line)
Contact Termination: Crimp
Fastening Type: Latch Lock

All identified substitute parts meet these mandatory parameters. Variations in color, insulation material composition, series designation, and product status are noted but do not preclude functional substitution. The substitute parts are drawn from two active product families: the Molex Mini-Fit Jr 5557 series and the TE Connectivity VAL-U-LOK series, both of which maintain electrical and mechanical compatibility with the original 0455870002 design.

Engineering Selection Recommendations

Molex Mini-Fit Jr 45587 Series (Same Series as Main Part):

The Molex 0455870004 is the primary substitute within the original Mini-Fit Jr 45587 series. This part maintains identical electrical and mechanical specifications to the 0455870002, including polyamide (PA) nylon insulation material and operating temperature range of -40°C to 105°C. The 0455870004 is Active in product status and ROHS3 Compliant, providing regulatory continuity for new designs and production applications.

Molex Mini-Fit Jr 5557 Series (Alternative Active Series):

The parts 0039012080, 0039013085, and 0039039082 represent the active Mini-Fit Jr 5557 series equivalent housings. All three maintain the mandatory parametric specifications for 8-position, 0.165" pitch receptacle connectors with crimp termination and latch lock fastening. These parts are ROHS3 Compliant and carry MSL 1 (Unlimited) ratings. The 0039012080 and 0039039082 specify polyamide (PA66) nylon 6/6 insulation, while 0039013085 includes glass-filled polyamide (PA66) nylon 6/6. Color variations (Natural for 0039012080; Black for 0039013085 and 0039039082) are available to match design requirements.

TE Connectivity VAL-U-LOK Series (Cross-Manufacturer Alternative):

The TE Connectivity 794954-8 provides a cross-manufacturer substitute from the VAL-U-LOK series. This part meets all mandatory parametric requirements and operates across the same temperature range (-40°C to 105°C) as the original 0455870002. The 794954-8 is RoHS Compliant and carries MSL 1 (Unlimited) rating, supporting both new production and field service requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0455870004 be used as a direct replacement for the obsolete 0455870002?

A: Yes. The 0455870004 is functionally equivalent to the 0455870002. Both parts are from the Mini-Fit Jr 45587 series, share identical connector type, contact type, position count, pitch, row configuration, mounting type, termination method, and fastening type. Both operate across -40°C to 105°C and carry MSL 1 (Unlimited) ratings. The 0455870004 is Active in product status and ROHS3 Compliant.

Q: What is the difference between the Molex Mini-Fit Jr 5557 series substitutes and the original 45587 series?

A: The Mini-Fit Jr 5557 series parts (0039012080, 0039013085, 0039039082) are from a different product line within Molex's Mini-Fit Jr family. All maintain identical electrical and mechanical parameters required for substitution. The primary differences are series designation, insulation material composition (PA66 nylon 6/6 versus PA nylon), and color options. All are ROHS3 Compliant and Active in product status.

Q: Is the TE Connectivity 794954-8 compatible with the original Molex 0455870002 design?

A: Yes. The 794954-8 meets all mandatory parametric requirements: 8-position receptacle, female socket contacts, 0.165" pitch, 2-row configuration, free hanging in-line mounting, crimp termination, and latch lock fastening. Operating temperature range (-40°C to 105°C) and MSL 1 (Unlimited) rating match the original part. Cross-manufacturer compatibility is established through parametric equivalence.

Q: Does color selection affect substitution eligibility?

A: No. Color is a cosmetic parameter that does not affect electrical or mechanical function. The 0455870002 is available in Black. Substitutes are available in Black (0039013085, 0039039082, 0455870004) and Natural (0039012080, 794954-8). Color selection should be based on design requirements and visual identification needs, not substitution compatibility.

Q: What is the significance of the insulation material variations among substitute parts?

A: Insulation material composition affects mechanical and thermal properties but does not preclude substitution when parametric specifications are met. The original 0455870002 uses polyamide (PA) nylon. Substitutes use either polyamide (PA) nylon (0455870004, 794954-8) or polyamide (PA66) nylon 6/6 (0039012080, 0039039082), with 0039013085 specifying glass-filled PA66 nylon 6/6. All materials support the specified operating temperature range and environmental requirements.

Q: Are all substitute parts ROHS compliant?

A: Yes. All identified substitute parts carry RoHS compliance certifications. The Molex parts (0039012080, 0039013085, 0039039082, 0455870004) are ROHS3 Compliant. The TE Connectivity 794954-8 is RoHS Compliant. This ensures regulatory compliance for new production applications in jurisdictions requiring RoHS adherence.

Q: What inventory considerations should guide part selection?

A: Inventory availability varies among substitutes. The 0039012080 has 213,760 units in stock, 0039039082 has 25,886 units, 0455870004 has 51,126 units, 0039013085 has 13,972 units, and 794954-8 has 2,100 units. Selection should balance availability with design requirements and lead time considerations.

Q: Can substitute parts be mixed within a single assembly?

A: All substitute parts are parametrically equivalent and maintain identical electrical and mechanical interfaces. Mixing substitute parts within a single assembly is permissible from a functional standpoint. However, design documentation and bill of materials should reflect the specific part numbers used to maintain traceability and support field service operations.
