Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF11G-18DP-2V(50) is determined by the following critical parameters:

• Connector type (Header), contact type (Male Pin), and position count (18 positions in 2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Mounting method (Surface Mount) and shrouding configuration (Shrouded - 4 Wall)
• Termination type (Solder) and electrical ratings (2A, 250V minimum)
• Operating temperature range compatibility (-30°C ~ 85°C minimum)
• RoHS compliance status

Two substitute parts meet these criteria:

DF11C-18DP-2V(57) – Hirose Electric Co Ltd manufacturer-recommended substitute with identical mechanical and electrical specifications, differing only in packaging format (Tape & Reel vs. Tube) and product status (Active vs. Last Time Buy).

0878321820 – Molex Milli-Grid 87832 series substitute offering equivalent form factor and functional compatibility with extended operating temperature range (-55°C ~ 105°C) and alternative contact geometry.

Parameter Comparison

Engineering Selection Recommendations

DF11C-18DP-2V(57) is the primary substitute for the DF11G-18DP-2V(50). Both parts are manufactured by Hirose Electric Co Ltd and share identical electrical and mechanical specifications. The DF11C-18DP-2V(57) maintains Active product status with higher inventory availability (1666 pcs vs. 759 pcs), ensuring long-term supply continuity. The only functional difference is packaging format: Tape & Reel (TR) versus Tube. This substitute is suitable for direct replacement in all applications where the original part was specified.

0878321820 (Molex Milli-Grid 87832) provides an alternative cross-platform substitute with equivalent form factor and electrical compatibility. This part offers an extended operating temperature range (-55°C ~ 105°C) compared to the original specification (-30°C ~ 85°C), making it suitable for applications requiring broader thermal performance. However, design validation is necessary due to differences in contact geometry (square vs. circular), contact material (phosphor bronze vs. brass), and insulation composition (glass-filled nylon). The Molex part carries ROHS3 compliance and maintains Active product status with substantial inventory (2278 pcs).

Frequently Asked Questions (FAQ)

Q: Can DF11C-18DP-2V(57) be used as a direct replacement for DF11G-18DP-2V(50)?

A: Yes. Both parts are Hirose Electric Co Ltd products with identical connector type, position count, pitch, row spacing, mounting method, shrouding, termination, and electrical ratings. The only difference is packaging format (Tape & Reel vs. Tube). No design changes are required.

Q: What are the key differences between DF11C-18DP-2V(57) and 0878321820?

A: Both maintain 18-position, 2-row, 2.00mm pitch configuration with surface mount solder termination. Key differences include: manufacturer (Hirose vs. Molex), contact shape (circular vs. square), contact material (brass vs. phosphor bronze), insulation composition (standard nylon vs. glass-filled nylon), operating temperature range (-30°C~85°C vs. -55°C~105°C), and fastening type (detent lock vs. latch holder). The Molex part requires design validation before implementation.

Q: Does packaging format affect electrical or mechanical performance?

A: No. Tape & Reel (TR) and Tube packaging formats contain identical connector components. Packaging selection is determined by assembly process requirements and inventory management practices, not by electrical or mechanical specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. DF11C-18DP-2V(57) is RoHS Compliant, and 0878321820 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: Which substitute should be selected for new designs?

A: DF11C-18DP-2V(57) is recommended for new designs due to identical specifications and active product status. The Molex 0878321820 is suitable only if extended operating temperature range (-55°C ~ 105°C) is a design requirement and cross-platform validation has been completed.
