Engineering Selection Recommendations

Direct Equivalents (Preferred for Replacement)

N3433-6002RB and D3433-6002-AR are the primary substitutes for the obsolete 3433-6002. Both are active products from 3M with identical core specifications. N3433-6002RB is RoHS Compliant and offers improved current rating (1.75A vs. 1A). D3433-6002-AR is ROHS3 Compliant with enhanced current capacity. Both maintain the required operating temperature range and UL94 V-0 flammability rating.

Cross-Manufacturer Alternatives

HARTING SEK series connectors (09185506904, 09185506912, 09185507904800) provide functional equivalence with extended operating temperature range (-55°C to 125°C). These parts feature latch lock fastening mechanisms instead of push-pull, which affects mating interface compatibility. Fastening type selection depends on application requirements.

Amphenol ICC 71918-050LF (Quickie™ series) offers push-pull fastening consistent with the original design. This part is RoHS Compliant and maintains gold mating contact finish with tin post finish.

CW Industries CWN series (CWN-350-50-0021, CWN-351-50-0021, CWN-352-50-0021) are ROHS3 Compliant alternatives with circular contact geometry and nickel post finish. These parts support extended temperature operation (-55°C to 125°C) and are available with push-pull or latch lock fastening options.

Compliance Considerations

All substitute parts except the original 3433-6002 meet RoHS requirements. For applications requiring ROHS3 compliance, D3433-6002-AR, HARTING SEK series, and CW Industries CWN series are suitable. N3433-6002RB and 71918-050LF meet RoHS Compliant status.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 3433-6002 with N3433-6002RB?

A: Yes. N3433-6002RB is a direct equivalent with identical electrical and mechanical specifications. The primary differences are active product status, RoHS compliance, and improved current rating (1.75A). Packaging differs (bulk vs. original), but functional performance is equivalent.

Q: What is the difference between push-pull and latch lock fastening types?

A: Push-pull fastening (3433-6002, N3433-6002RB, D3433-6002-AR, 71918-050LF, CWN-350-50-0021) uses a simple push-to-mate, pull-to-disconnect mechanism. Latch lock fastening (HARTING SEK series, CWN-351-50-0021, CWN-352-50-0021) uses eject hooks for positive mating retention. Fastening type affects connector interface design and must match the mating receptacle.

Q: Are HARTING SEK series connectors compatible with the original 3433-6002 receptacles?

A: HARTING SEK series connectors share identical pitch (0.100"), position count (50), and row spacing (0.100") with the 3433-6002. However, the latch lock fastening mechanism differs from the original push-pull design. Compatibility depends on whether the mating receptacle supports latch lock engagement. Mechanical interference may occur if receptacles are designed exclusively for push-pull fastening.

Q: What is the significance of contact material differences (copper alloy vs. phosphor bronze)?

A: Contact material affects electrical conductivity, spring force retention, and wear characteristics. Copper alloy (3433-6002, N3433-6002RB, HARTING SEK series) and phosphor bronze (71918-050LF, CW Industries CWN series) both meet the 1A current requirement. Material selection does not affect functional substitution for standard applications.

Q: Why do some substitute parts have higher current ratings?

A: N3433-6002RB and D3433-6002-AR are rated for 1.75A compared to the original 1A rating. This reflects improved contact design and material specifications in active production parts. Higher current rating provides design margin but does not affect compatibility with 1A-rated applications.

Q: Is the extended operating temperature range (-55°C to 125°C) of HARTING and CW Industries parts a compatibility concern?

A: No. Extended temperature range is a superset of the original -55°C to 105°C specification. Parts rated for -55°C to 125°C are fully compatible with applications requiring -55°C to 105°C operation. This represents an improvement in thermal capability.

Q: What packaging options are available for substitute parts?

A: N3433-6002RB is supplied in bulk packaging. D3433-6002-AR is supplied in trays. HARTING 09185506904 is supplied in trays; 09185506912 and 09185507904800 are supplied in bulk. Amphenol ICC 71918-050LF is supplied in tubes. CW Industries CWN series packaging is not specified. Packaging selection affects handling and storage but does not affect electrical or mechanical performance.

Q: Are all substitute parts RoHS compliant?

A: No. The original 3433-6002 is RoHS non-compliant. N3433-6002RB and 71918-050LF are RoHS Compliant. D3433-6002-AR, HARTING SEK series, and CW Industries CWN series are ROHS3 Compliant. For applications requiring RoHS compliance, select from the compliant alternatives listed.
