Key Parameters

Substitute Part Grouping Explanation

The Molex 0307004200 qualifies as a direct functional substitute for the 0307004201 based on the following critical parameters:

Matching Parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (20 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting method and termination (Through Hole, Solder)
• Shrouding design (Shrouded - 4 Wall)
• Contact material and finish (Copper Alloy, Tin)
• Insulation material (Syndiotactic Polystyrene, Glass Filled)
• Compliance certifications (ROHS3, MSL 1)
• Series designation (H-DAC 64 30700)

Distinguishing Factor: The primary difference is product status: the 0307004201 is obsolete, while the 0307004200 is active. The 0307004200 also features gray insulation versus black insulation on the original part. Both variants maintain identical electrical and mechanical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0307004200 is the recommended substitute for the obsolete 0307004201. Both parts maintain identical electrical and mechanical interface specifications, ensuring direct compatibility in existing designs. The 0307004200 is currently in active production status with confirmed inventory availability, addressing the supply discontinuation of the original part.

Both variants satisfy ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment for automotive applications. The MSL 1 rating on both parts indicates unlimited shelf life under standard storage conditions.

The insulation color difference (gray versus black) is a cosmetic distinction that does not affect functional performance or electrical characteristics. Component selection should be based on design documentation requirements and visual identification protocols specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 0307004200 be used as a direct replacement for the 0307004201?

A: Yes. The 0307004200 provides identical electrical and mechanical interface specifications. Both parts feature the same 20-position, 2-row header configuration with 0.100" (2.54mm) pitch, through-hole solder termination, and shrouded 4-wall design.

Q: What is the significance of the insulation color difference?

A: Insulation color is a visual identification feature only and does not affect electrical performance, mechanical fit, or signal integrity. The gray insulation on the 0307004200 versus black on the 0307004201 is a cosmetic distinction.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 0307004201 and 0307004200 maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity ratings.

Q: Why is the 0307004201 listed as obsolete?

A: The 0307004201 has been discontinued by Molex. The 0307004200 represents the active production equivalent within the same H-DAC 64 30700 series.

Q: What packaging is available for the substitute part?

A: The 0307004200 is supplied in bag packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Are the contact dimensions identical between both parts?

A: Yes. Both parts feature identical contact geometry: 0.311" (7.90mm) mating length, 0.145" (3.68mm) post length, and 0.692" (17.58mm) overall contact length. Mated stacking height is 26.22mm for both variants.
