Molex 0022285021 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022285021 is a vertical through-hole rectangular connector header with 2 positions at 0.100" (2.54mm) pitch. This unshrouded, breakaway header is designed for board-to-board or cable applications in automotive, general purpose, medical, and telecommunications sectors. The part is active in production status and ROHS3 compliant with UL94 V-0 flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022285021 is determined by strict alignment of the following critical parameters:

Connector type classification (Header, Breakaway or Header, Cuttable)
Contact type (Male Pin)
Pitch specification (0.100" / 2.54mm)
Number of positions (2)
Number of rows (1)
Mounting method (Through Hole)
Termination method (Solder)
Fastening type (Push-Pull)
Shrouding configuration (Unshrouded)
Contact shape (Square)
Flammability rating (UL94 V-0)
RoHS compliance status

All identified substitute parts meet these core electrical and mechanical criteria. Variations in contact length, insulation height, contact finish composition, and operating temperature ranges do not preclude substitution when the primary functional parameters remain constant.

Engineering Selection Recommendations

All identified substitute parts maintain active production status and comply with RoHS regulations. The Molex 0022285021 and all substitute options carry UL94 V-0 flammability certification and unlimited moisture sensitivity classification, meeting the same compliance framework.

TE Connectivity 826629-2 and Amphenol ICC 861400021YO8LF represent breakaway header variants with gold contact finishes, providing enhanced corrosion resistance compared to the tin-finished original part. The Amphenol ICC option extends operating temperature range to -55°C ~ 125°C and specifies 1000V voltage rating.

Harwin M20 series options (M20-9730245, M20-9730246, M20-9990245, M20-9990246) are classified as cuttable headers rather than breakaway, offering design flexibility for custom position configurations. The M20-9730245 and M20-9730246 variants maintain 0.276" (7.00mm) mating contact length, while M20-9990245 and M20-9990246 feature reduced 0.240" (6.10mm) mating contact length. Tin and gold finish options are available across the M20 lineup. All Harwin parts specify 3A per contact current rating and operate across -40°C ~ 105°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can I substitute a Harwin M20 cuttable header for the Molex 0022285021 breakaway header?

A: Yes. Both connector types share identical pitch (0.100" / 2.54mm), position count (2), row configuration (1), mounting method (through hole), termination (solder), fastening type (push-pull), and shrouding (unshrouded). The functional difference between breakaway and cuttable designs does not affect electrical or mechanical compatibility in applications where the 2-position configuration is required.

Q: What is the significance of contact length variations among substitute parts?

A: Contact length variations reflect different mating depths and post lengths across manufacturers. The Molex 0022285021 specifies 0.320" (8.13mm) mating contact length, while substitutes range from 0.240" to 0.276". These differences do not affect substitution eligibility when mating surfaces and pitch alignment remain constant. PCB layout and connector receptacle design should be verified to ensure mechanical fit.

Q: Are gold-finished contacts superior to tin-finished contacts?

A: Gold contact finishes provide enhanced corrosion resistance and lower contact resistance compared to tin finishes. Selection between gold and tin finishes depends on application environment and electrical performance requirements. Both finishes are acceptable substitutes when the base connector geometry and electrical specifications align.

Q: Does the operating temperature range difference affect substitution?

A: The Molex 0022285021 does not specify an operating temperature range. Substitute parts specify ranges from -40°C ~ 105°C (Harwin M20 series) to -55°C ~ 125°C (Amphenol ICC). When the original part lacks temperature specification, substitute parts with defined operating ranges provide documented thermal performance. Application thermal requirements should be evaluated against substitute specifications.

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

A: ROHS3 Compliant indicates compliance with the third iteration of the Restriction of Hazardous Substances directive, incorporating additional restricted substances. RoHS Compliant indicates general RoHS compliance without specifying the directive version. Both designations confirm hazardous substance restrictions; ROHS3 represents the current regulatory standard.

Q: Can I use substitute parts with different insulation materials?

A: Yes. The Molex 0022285021 specifies polyamide (PA) nylon with glass filling, while substitutes use polybutylene terephthalate (PBT), thermoplastic, or polyamide (PA6T) nylon 6T. All materials meet UL94 V-0 flammability requirements. Material selection affects mechanical properties and environmental resistance; application-specific requirements should be evaluated.

Q: Are all substitute parts available in equivalent packaging quantities?

A: Substitute parts are supplied in bulk packaging. Inventory levels vary by manufacturer and distributor. The Molex 0022285021 shows 1125 pieces in stock, while substitute availability ranges from 695 to 135,364 pieces depending on the specific part number and supplier.
