Substitute Part Grouping Explanation

Substitute parts for the MF1/4DC4702F are classified based on electrical and mechanical parameter equivalence:

Parametric Equivalent: MF1/4DCT52R4702F differs only in packaging format (Cut Tape vs. Bulk). All electrical specifications, physical dimensions, and automotive qualifications remain identical. This substitution is valid for applications where packaging format does not impose design constraints.

Similar Equivalent: RNMF14FTC47K0 maintains electrical equivalence (47 kOhms ±1%, 0.25W, metal film, axial) and automotive qualification (-55°C to 155°C operating range). Physical dimensions differ (0.070" Dia x 0.130" L vs. 0.091" Dia x 0.248" L), and temperature coefficient is improved (±50ppm/°C vs. ±100ppm/°C). This substitution requires verification of board layout compatibility due to dimensional variance.

Key parameters determining substitution validity:

• Resistance value and tolerance
• Power rating
• Composition type (metal film)
• Package configuration (axial through-hole)
• Operating temperature range
• Automotive qualification status
• RoHS compliance

Engineering Selection Recommendations

MF1/4DCT52R4702F Selection: This part is recommended as a direct substitute when packaging format flexibility exists. Identical electrical performance and physical dimensions ensure drop-in compatibility. Higher inventory availability (5,764 units) may provide supply chain advantages. Both parts maintain AEC-Q200 automotive qualification and ROHS3 compliance.

RNMF14FTC47K0 Selection: This part is suitable for applications where compact form factor is beneficial. The smaller physical dimensions (0.070" Dia x 0.130" L) enable space-constrained board layouts. The improved temperature coefficient (±50ppm/°C) provides enhanced stability in temperature-sensitive circuits. Board layout verification is required due to dimensional differences. RoHS3 compliance is confirmed; automotive qualification status should be verified against specific application requirements.

All substitute parts maintain the required 47 kOhms ±1% resistance specification, 0.25W power rating, metal film composition, and -55°C to 155°C operating temperature range necessary for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can MF1/4DCT52R4702F replace MF1/4DC4702F directly? A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape vs. Bulk). No design modifications are required.

Q: What are the dimensional differences between MF1/4DC4702F and RNMF14FTC47K0? A: MF1/4DC4702F measures 0.091" Dia x 0.248" L (2.30mm x 6.30mm). RNMF14FTC47K0 measures 0.070" Dia x 0.130" L (1.78mm x 3.30mm). The RNMF14FTC47K0 is significantly smaller and may require PCB layout adjustment for hole spacing and component clearance.

Q: Are all substitute parts AEC-Q200 qualified? A: MF1/4DC4702F and MF1/4DCT52R4702F are both AEC-Q200 qualified. RNMF14FTC47K0 automotive qualification status is not specified in the provided data and should be confirmed for automotive applications.

Q: What is the temperature coefficient difference, and does it matter? A: MF1/4DC4702F and MF1/4DCT52R4702F have ±100ppm/°C temperature coefficient. RNMF14FTC47K0 has ±50ppm/°C. The lower coefficient in RNMF14FTC47K0 indicates better resistance stability across temperature variations, beneficial for precision circuits. For general applications, both are acceptable.

Q: Are all parts RoHS compliant? A: Yes. MF1/4DC4702F, MF1/4DCT52R4702F, and RNMF14FTC47K0 are all ROHS3 compliant.

Q: Which substitute should I choose for a new design? A: For electrical equivalence with identical dimensions, select MF1/4DCT52R4702F. For space-constrained applications requiring compact form factor, select RNMF14FTC47K0 after verifying PCB layout compatibility and confirming automotive qualification requirements.
