Substitute Part Grouping Explanation
Substitution eligibility for the 3M 3428-5303 is determined by the following critical parameters:
Primary Matching Criteria:
- 20 positions, 2 rows at 0.100" (2.54mm) pitch and row spacing
- Through-hole, right-angle mounting configuration
- Shrouded 4-wall construction
- Solder termination
- Square contact shape
- Gold mating contact finish
- UL94 V-0 flammability rating
- MSL 1 (Unlimited)
Secondary Compatibility Parameters:
- Contact length variations (mating contact fixed at 0.240" / 6.10mm; post length may vary)
- Fastening type (latch lock/eject hooks long, short, or push-pull configurations)
- Insulation material (PCT or PBT, both glass-filled)
- Operating temperature range (minimum -55°C to 105°C or higher)
- Contact material (copper alloy or brass)
- Post contact finish (tin or tin-lead)
Substitute parts meeting all primary criteria are functionally compatible. Secondary parameter variations reflect design alternatives that maintain electrical and mechanical interchangeability within the specified pitch and position configuration.

Engineering Selection Recommendations
3M Active Alternatives (Recommended for RoHS Compliance):
The 3M D3428-5002-AR and N3428-5002RB are direct active-status replacements for the obsolete 3428-5303. Both maintain the 20-position, 2-row 0.100" pitch configuration with identical mating contact length and insulation height. The primary differences are fastening type (push-pull versus latch lock/eject hooks) and contact post length variation. Both parts are ROHS3 compliant, addressing regulatory requirements that the original part does not meet. The D3428-5002-AR is packaged in trays, while N3428-5002RB is supplied in bulk.
HARTING SEK Series Alternatives (Extended Temperature Range):
The HARTING 09185205901, 09185205911, 09185205913, 09185206901, 09185206903, 09185206903001, 09185206911, and 09185206913 connectors provide functional equivalence with extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). These parts maintain the critical 20-position, 2-row 0.100" pitch and 0.240" mating contact length. Variations exist in contact post length (0.114" or 0.177"), fastening mechanism (latch lock/eject hooks long or short, or latch holder), and insulation material (PBT versus PCT). All HARTING parts are ROHS3 compliant and carry REACH Unaffected status. The 09185206913 offers the highest inventory availability at 2332 pieces.
Compliance Considerations:
All substitute parts listed are ROHS3 compliant, making them suitable for applications requiring regulatory adherence. The original 3428-5303 is RoHS non-compliant and should be replaced in new designs or production runs subject to RoHS directives.
Frequently Asked Questions (FAQ)
Q: Can I directly replace the 3M 3428-5303 with any of the listed substitutes?
A: Yes, all listed parts are functionally compatible based on matching the critical parameters: 20 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing, through-hole right-angle mounting, shrouded 4-wall construction, and solder termination. Mechanical fit and electrical performance are maintained across all substitutes.
Q: What is the difference between the 3M D3428-5002-AR and N3428-5002RB?
A: Both are active 3M alternatives with identical electrical and mechanical specifications. The primary differences are packaging (D3428-5002-AR supplied in trays; N3428-5002RB supplied in bulk) and fastening type (D3428-5002-AR uses push-pull; N3428-5002RB uses latch lock/eject hooks). Select based on packaging requirements and connector engagement preference.
Q: Why do HARTING parts have a higher operating temperature range?
A: HARTING SEK series connectors are rated to -55°C to 125°C, compared to the original part's -55°C to 105°C. This extended range reflects the design specifications of the HARTING product line and provides additional thermal margin for demanding applications.
Q: What is the significance of contact post length variations?
A: Contact post length (0.112", 0.114", 0.155", or 0.177") determines the depth of solder joint penetration on the PCB. Variations accommodate different PCB thicknesses and solder joint requirements. All listed post lengths are compatible with standard PCB assembly processes.
Q: Are all substitute parts RoHS compliant?
A: Yes. All substitute parts listed are ROHS3 compliant. The original 3428-5303 is RoHS non-compliant and should be replaced in applications subject to RoHS directives.
Q: What is the difference between latch lock/eject hooks (long), latch lock/eject hooks (short), and push-pull fastening?
A: These represent different mechanical engagement mechanisms. Latch lock/eject hooks (long and short variants) provide positive locking with manual ejection capability. Push-pull fastening offers simplified engagement and disengagement. Selection depends on application requirements for connector retention and serviceability.
Q: Can I mix contact post lengths in the same application?
A: Contact post length is a design parameter that should remain consistent within a connector assembly to ensure uniform solder joint quality and mechanical stability. Mixing post lengths is not recommended.
Q: What packaging options are available?
A: The 3M D3428-5002-AR is supplied in trays. The 3M N3428-5002RB and all HARTING parts are supplied in bulk. Select packaging based on production volume and handling requirements.
Q: Are HARTING parts suitable for applications requiring REACH compliance?
A: Yes. All HARTING parts listed carry REACH Unaffected status, indicating compliance with REACH regulations.
